Abstract
Description
Technical Field
The invention relates to a crystal form of a thienoimidazole compound and a preparation method thereof, and also comprises application of the crystal form in preparation of medicaments for treating related diseases.
Background
Diabetes mellitus is a common metabolic disease characterized by hyperglycemia. Several major types of diabetes are caused by complex interactions between genetic and environmental factors. Factors causing hyperglycemia include a decrease in insulin secretion ability, a decrease in glucose utilization ability, and an increase in glucose output, which are mainly attributed to the cause of diabetes. Metabolic abnormalities associated with diabetes lead to secondary physio-physiological changes in multiple systems throughout the body. Long-term abnormal blood glucose levels can lead to serious complications, including cardiovascular disease, chronic renal failure, retinal damage, nerve damage, microvascular damage, obesity, and the like. The classification of diabetes is based on different pathological processes leading to hyperglycemia and can be divided into two main types, type 1 diabetes and type 2 diabetes. Type 1 and type 2 diabetes mellitus are characterized by abnormal glucose homeostasis prior to onset during the course of the disease. Type 1 diabetes is the result of complete or almost complete insulin deficiency. Type 2 diabetes is a heterogeneous group of diseases that manifest in varying degrees of insulin resistance, decreased insulin secretory function, and increased glucose production. Treatment of diabetes, early stage, diet control and exercise therapy are the preferred glycemic control regimens. When these methods are difficult to achieve blood glucose control, treatment with insulin or oral hypoglycemic drugs is required. Currently, drugs for the treatment of diabetes include insulin, insulin secretagogues, metformin, insulin sensitizers, α -glucosidase inhibitors, dipeptidyl peptidase-IV inhibitors (statins), sodium-glucose co-transporter (SGLT 2) inhibitors, and glucagon-like peptide-1 (GLP-1) receptor agonists, and the like. These drugs have good therapeutic effects, but have safety problems in long-term treatment, for example, biguanides are liable to cause lactic acidosis; sulfonylureas can cause hypoglycemic symptoms; insulin sensitizers can cause edema, heart failure and weight gain; alpha-glucosidase inhibitors can cause symptoms such as abdominal pain, abdominal distension, diarrhea, and the like; sodium-glucose co-transporter (SGLT 2) inhibitors increase the risk of urinary, reproductive infections, and the like. Therefore, a safer and more effective novel hypoglycemic medicament is urgently needed to be developed to meet the treatment requirement of diabetes.
The glucagon-like peptide-1 receptor (GLP-1R) is one of the most important therapeutic targets for type 2 diabetes. GLP-1R belongs to a member of the B cluster subfamily of G protein coupled receptors and is widely expressed in tissues such as stomach, small intestine, heart, kidney, lung, brain and the like in vivo. In islet cells, GLP-1R is mainly used for promoting the release of insulin, increasing the regeneration of islet B cells, inhibiting the apoptosis of B cells and reducing the release of glucagon. In tissues such as the gastrointestinal tract, GLP-1R can inhibit the peristalsis and gastric fluid secretion of the gastrointestinal tract by combining with an agonist thereof, delay gastric emptying and increase satiety. In neural tissue, small molecule GLP-1R agonists can penetrate through the brain to activate the neuron subset expressed by GLP-1R, protect the apoptosis of nerve cells and strengthen the learning and memory ability. Moreover, GLP-1R also controls food intake to reduce body weight. GLP-1 receptor agonists or endogenous GLP-1 activity enhancers are approved for the treatment of type 2 diabetes. Such drugs do not cause hypoglycemia because secretin-stimulated insulin secretion is glucose-dependent. Exenatide is an artificially synthesized peptide, originally found in lizard saliva, which is a GLP-1 analog. Exenatide has a different amino acid sequence compared to native GLP-1, making exenatide resistant to enzymes that degrade GLP-1 [ dipeptidyl peptidase IV (DPP-IV) ]. Therefore, exenatide has a prolonged GLP-1 like activity and can bind to GLP-1 receptors in the pancreatic islets, gastrointestinal tract, brain. Liraglutide, another GLP-1 receptor agonist, is almost identical to native GLP-1 except that it replaces one of the amino acids and adds a fatty acyl group, which promotes its binding to albumin and plasma proteins and prolongs half-life. GLP-1 receptor agonists increase glucose-stimulated insulin secretion, inhibit glucagon, and delay gastric emptying. These drugs do not increase body weight, and in fact, most patients experience some degree of weight loss and loss of appetite. DPP-IV inhibitors inhibit the degradation of native GLP-1, thereby enhancing the effect of secretin. DPP-IV, which is well expressed on the cell surface of endothelial cells and some lymphocytes, can degrade a wide variety of polypeptides (not only GLP-1). DPP-IV inhibitors promote insulin secretion without lowering blood glucose, without increasing body weight, and are more advantageous in lowering postprandial blood glucose. Patients with GLP-1 receptor agonists have higher levels of GLP-1 effect in vivo than patients with DPP-IV inhibitors.
The small molecule GLP-1 receptor stimulant with oral activity is developed, long-term self injection of patients can be effectively avoided, and good compliance is achieved. The small molecule GLP-1 receptor stimulant controls blood sugar through a plurality of ways of glucose metabolism and excretion, and is expected to develop a safer and more effective novel blood sugar reducing medicine to meet the treatment requirement of diabetes.
